Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.

Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.

Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.

If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.

Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.

Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.

Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.

If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.

No advertising or soliciting.

We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.

When answering a question please:

Read the question carefully

Understand that English isn't everyone's first language so be lenient of bad spelling and grammar

If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome

If the question is inappropriate then click the 'vote to remove message' button

Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.

So I want to program an app, where I use the tweepy api. On the frontend of the app, I want to display a list of objects on which can be pressed. If one of them is pressed one new page will open and there I want to display some integer values, which are updating depending on some tweets.

So in the backend I have tweepy where I program with python and the frontend. I started to work with the django framework + react but I do not know if this is the best way to program an app like that. Could you give me some advices on which framework I should use?

On my home page ( [DELETED] )...the Navigation Bar scrolls correctly on any computer display. But on any cell phone, it will not scroll upward and out of the way of the content below it (content which is very important to view fully).

Don't post your website here unless you want us to consider you a spammer and throw you off.
I was that close with this one as it was, but you've been here a while so I decided to warn you instead. Others have a twichier trigger finger, so unless you refrain from doing it in future (and I include text-based "non link URL's" like some of your previous posts in this) it is inevitable that you will be kicked off the site at some point. The automated system we have in place now doesn't like them, and that means your posts will go direct to the tender mercies of whoever sees it in moderation first. That won't always be me ...

Post the relevant code fragments in your message - use the code widget above the text box, and that'll engage the syntax highlighter and preserve any formatting.
Like this:

<pre lang="cs">int Double(int x)
{
return x + x;
}</pre>

Will show as:

intDouble(int x)
{
return x + x;
}

It's not a good idea to post the whole code anyway - people are more likely to respond if you show them where the problem is instead of dumping a whole app on them and saying "it don't work".
Remember, we can't generally run your whole code anyway - we don't have your site, your data, your user inputs - and we don't know what it should do or how to get to the problem area.

The better you make the question, the better we can make the response - and wading through pages of irrelevant code trying to work out what bit of it matters doesn't encourage people to be helpful!

I. How to migrate an existing project to AndroidX
In Android Studio 3.2 and higher, you can quickly migrate an existing project to use AndroidX by selecting Refactor -> Migrate to AndroidX from the menu bar.

If you want to use AndroidX in a new project, you need to set the compile SDK to Android 9.0 (API level 28) or higher and The following Android Gradle plugin flags to true in your gradle.properties file.

set android.enableJetifier=true , the Android plugin automatically migrates existing third-party libraries to use AndroidX by rewriting their binaries. android.useAndroidX is false by default if it is not specified.
